    Re: DOF on 8x10 vs. 4x5?

    I don't think you have muddied the water, but I would add, in your scenario of same lens and position, is that the prints must also be the same ratio size as 4x5 is to 8x10 so that the end result...

    Focal length is the Fstop times the measured diameter of the aperture (from the front) at that Fstop. I think so anyway. Assuming the shutter is labelled correctly.
